As thousands of regular citizens descended on airports across the country Saturday night, they were not alone.

Several members of Congress joined the protests at airports in their home states, including Sen. Elizabeth Warren (D-Mass.) and Rep. John Lewis (D-Ga.).

Both influential members were spotted showing their opposition to the the immigration ban. Fox 5 Atlanta reporter Marissa Mitchell posted on Twitter that Lewis told her, "he's going to sit at airport and wait for info on delays for processing Iranian families returning home."

In a video posted to Warren's Twitter feed, the senator is seen leading the crowd at Boston's Logan International Airport in a chant against the ban.

"It is illegal, it is unconstitutional and it will be overturned," Warren said in the video.

Many have decried the ban, an executive order that went into effect early on Saturday before being halted that night, as a ban against Muslims. The seven countries that were included in the ban all have predominately Muslim populations.

"We will not turn away anyone because of their religion," chanted Warren.

Warren and Lewis were not alone. Rep. Suzan DelBene (D-Wash.) shared a picture of her and fellow congresswomen Pramila Jayapal at Seattle's Seattle-Tacoma International Airport trying to get answers about the ban.

Several other members of Congress took to the social media platform to voice their opinions on the ban, as did Hillary Clinton.

"I stand with the people gathered across the country tonight defending our values & our Constitution," the former presidential candidate wrote on Twitter late Saturday night in a tweet that has been retweeted more than 28,000 times. "This is not who we are."

I stand with the people gathered across the country tonight defending our values & our Constitution. This is not who we are.
